| 中文摘要: |
| 研究硅烷偶联剂KH570和WD-10对三元乙丙橡胶（EPDM）/硅橡胶（MVQ）并用胶性能的影响。结果表明：偶联剂KH570能同时增强填料间、填料-橡胶间的相互作用，但不利于填料分散和降低胶料生热；偶联剂WD-10不能明显增强填料-橡胶间的相互作用，但惰性长链烷基的存在可以使填料的分散更为稳定；偶联剂KH570与WD-10并用时，能获得
综合物理性能和耐高温老化性能优异的EPDM/MVQ耐高温复合材料。 |
| 英文摘要: |
| The effect of silane coupling agent KH570 and WD-10 on the properties of EPDM/MVQ blend was investigated. The results showed that，coupling agent KH570 was much more effective for improving the filler-filler and filler-rubber interactions，but was not good for filler dispersion and decreasing the heat build-up. With coupling agent WD-10，the filler-rubber interaction was not greatly increased，but its long non-reactive chain was believed to enable the steady dispersion state of fillers. It was found that blending of coupling agent KH570 and WD-10 was an ideal way to obtain EPDM/MVQ composite with excellent comprehensive physical properties and high temperature aging resistance. |
